Particle and Fluid Forces driven by motion vector image data (XYZ vectors). Optical Flow
hmm just brainstorming.  Convert motion vectors to points use those points (make sure to keep points to a limited number) to act as effectors in a fluid sim. So you have to probably write a script that converts pixel location x,y,z data into points.  There is software out there but that's the extent of my knowledge on this.  

I use this with the depth data from structure scanner to make a per frame point cloud.  It might work with standard motion vectors. Its a start.
